UK Electoral Roll Compilation Dates

UK Electoral Roll Compilation Dates

Does anybody know where I can find information on when an Electoral Roll was compiled? One of my ancestors was on the 1937 electoral roll but not on the 1938 roll, and I have been struggling to find his death as the rest of the family remain at the same address. I was just hoping that a rough ideas of dates would give me a better chance of finding it.Thanks,Vanessa
